    摘要:

    针对基于压缩数据采集的数据聚合需要高效的路由转发树协议,以便更好地采集到从传感器节点到sink节点的编码数据,提出了一种新型高效节能的分布式压缩数据收集方法。该方法中每个传感器节点均可独自寻找父节点,并构建一部分路由树,无需利用中心节点来构建所有转发树,从而允许每个传感器节点对转发树的构建和维护做出局部决策。仿真实验结果表明,相比传统的压缩数据收集方法,新方法的复杂性较低并且开销降低近50%。

    Abstract:

    Data aggregation based on compressed data collection need efficient routing forwarding tree protocol to gather the coded data corresponding to the sensor nodes to the sink node effectively. A new distributed compressed data collection method with high efficiency and energy saving is presented. Each sensor node can be found alone in the part of its parent and able to build a routing tree, without using the center node to build all forwarding tree, which allows each sensor node to make local decisions on the forwarding tree construction and maintenance. Simulation results show that the complexity of the new method is lower compared with that of the traditional method, and the cost reduces nearly 50%. 
